WALL.

Application filed December 17, 1927, Serial No. 240,667, and in Germany May 2, 1927.

My invention relates to improvements in walls or ceilings and the method of making ing the same. More particularly my invention relates to walls or ceilings consisting .5 of pairs of superposed lianged glass tiles united by a suitable mortor, and the object of the improvements is to provide a wall-or ceiling in which 'in case of breakage a sectional tile can be readily removed without endangering the other tiles. Another object of the improvements is to construct the wall or ceiling so that the mortar has no access to the gap provided between the contacting faces of the sectional tiles of the pairs. .With these objects in view my invention consists in covering the said gap before applying the mortar to the spaces provided between adjacent pairs of sectional tiles by suitable matter such as strips of linen or the like, so that when filling the spacesv between the pairs of sectional tiles with mortar the said mortar isprevented from passing into the gaps, and further, the said gaps are kept clean, so that the light rays can freely pass through the same. Thus, the wall or ceiling has a clear appearance, because the light rays passing through the gaps are not interrupted in an irregular way by parts of mortar pressed into the said gaps. Further, when one of the sectional tiles is broken it can be readily removed without injuring the superposed sectional tile, because the said sections are not directl connected with each other, and the thic body of mortar holding adjacent tiles together is readily broken.

Preferably, the strip of-linen or the like used for covering the gap 1s coated at its inner face with a suitable binding medium capable of adhering to glass. Thusthe superposed sectional tiles are connected with each other by the said strip, so that they are not separated from each other when assembling the same into a wall or ceiling. For the purpose of explaining the invention several examples embodying the same have been shown in the accompanying drawing in which the same letters of reference have been usedl in all the views to indicate corresponding parts. In said drawing, l Fig. 1, is a top plan view partly in sec.- tion showing a tile and a strip of linen orl the like applied to the tile,

Fig. 2, is a sectional elevation on an en' larged scale taken on the' line 2-2 of Fig. 1, Fig. 3, is a similar sectional elevation terial, the said showing a wall or ceiling made by assem bling pairs of sectional tiles, i

Fig. 4, is a top plan view of a ceiling, and Fig. 5, is a sectional elevation similar tol the one illustrated in Fig. B 'and showing a modification of the tiles. l

In the example shown in Figs. 1 to 3, the glass tile consists of two sectional tiles a and b each formed about its circumference with a flange g, both sectional tiles being concave at their adjacent sides, as is shown at a, and formed around said cavity with a ribr. Said ribs are formed respectively with inner and outer ridges s, t, and when placing the sectional tiles together the outer ridge t.

embraces the inner ridge s. Thus displacement of the sectional tiles parallel to the plane thereof is impossible. When assembling the sectional tiles a gap f is provided between the same which is comparatively narrow only if the abutting faces of the sectional tiles are perfectly plane. -However, in the manufacture the sectional tile are deformed more or less, so that the gap will ordinarily be comparatively broad at various parts of the abutting faces.

,lVhen building a ceiling or a wall from the pairs of tiles a, b, the said pairs of tiles are placed one beside the other, and the space provided between the flanges g is filledv out with a. suitable mortar h such as hydraulic cement, and in some cases the mortar is reinforced by iron rods c'.

Now, in my improved construction the gap f provided between the sectional tiles a and b after placing the same together, is coated by means of a strip lo of suitable mastrip being provided at its inner face with a suitable binding medium or glue. The strip lo, fm. must/be of such nature that it is not dissolved by the mortar Il., and in any case its impermeability to water must be such that when assembling the pairs of tiles a and b to provide a wall or ceiling therefrom, the liquid contained in the mortar has/no access to the gap f until the mortar has set.v Further, the binding medium or glue m must be of such nature that it sticks to glass. Y

The 4method of applying the strip to thel pair of tiles has been illustrated in Fig. 1. As shown, the strip k, m is taken from a roll thereof, and it is wound around the gap f of the tile a, b, so that the ends slightly overlap each other. Since the strip rigidly adheres to the side faces of the sectional tiles aia-nd b the ga f is'perfectl closed. Further, the sectiona tiles arefixe to each other so that the can not be separated transversely of the p ane thereof, so that the tile can be readily assembled-into a wall.

The plastic mortar lu poured or pressed into the s aces provided between adjacent tiles and t e flanges g thereof can not get into the gap f covered by the strip le, m. If therefore one of the sectional tiles a, or b cracks the broken sectional tile can be readily broken out of the-wall without injuring the other sectional tile, 'because the said sectional tiles are merely connected with each other by the strip k, mr and'their abutting 'faces are not connected by any mortar. Further, the. sectional tile which is not broken is rigidly held Within the wall. Preferably the rib 1' and ridges t are slighty tapering, so' that the broken tile can be rea ily removed from the wall. body of morta-r la. is readily broken away. Thusan injured part of the wall can lbe readily re aired. Further, the abutting faces d, c of t e tiles a are transparent, so that the wall permits a large part of light to pass through the same, and the tiles are clean, so that the whole wall has a clear appearance.

In the modification shown in Fig. 5 the sectional tiles are constructed so that they are connected with each other in the factory, a ring n of concrete or hydraulic cement being applied to the side faces of the sec- Further, the

tional tiles after putting the same together. Before applying the said concrete the ga f is covered by means of a, strip of paper in the manner described with reference to Figs. l to 3. It will be understood that. it is not always necessary to coat the said strip with glue, and vthat in many cases the strip will sufficiently cover the gap by being tightly laid around the pair of tiles.

This disclosure is an improvement on the invention covered by my copending'application, Serial N o. 180,126, filed April 1, 1927,

which matured into Patent No. 1,667,484, dated April 24, 1928.

I claim:

l. The herein described wall or ceiling composed of pairs oflsuperposed sectional glass tiles having the ga formed between the abutting faces thereo closed at its outside by a strip of 1a.suitable material glued to the side faces :of the sectional, tiles, and a mass of mortar filling out the spaces between adjacent pairs of sectional tiles.

2. A tile comprising two superposed sectional glass tiles, a strip of suitable 4material for closing the gap provided betweenthe abutting faces of said sectional tiles at their outside, said strip being glued to the side faces of the sectional tiles, and a suitable cement applied to the side faces of the sectional tiles for holding the same together.

Signed at Berlin, this 27th day of September, 1927.
